The instillation of local anesthetic into the peritoneum has been found to be safe and effective in reducing postoperative pain and morphine consumption after abdominal surgery. A review of studies reporting serum levels of local anesthetic after intraperitoneal delivery found no cases of clinical toxicity in any of the trials. The studies in this meta-analysis did not include post-cesarean delivery pain and there is a lack of data to support the use of intraperitoneal local anesthetic after cesarean section.
